Title: Support for running JOP from DRAM

THe altde2dram quartus project enables use of DRAM as sc_mem. Minor changes in mem_sc.vhd where necessary to make mem_sc fully compatible with SimpCon specification. The frontend of the dram controller relies in its current development state on the ability to switch rdy_cnt from 3 to 0 without intermediate stages. The reason for this can be found in the nextstate logic of state ialrb in mem_sc.vhd. The first if condition is not correct in the situation where rdy_cnt is 0.
